T-Mobile CEO John Legere took to his company’s newsroom today to talk about how his crew is “firing on all cylinders.” In other words, T-Mobile is still killin’ it for the most part.

The wireless carrier added another 1.5 million new customers in the last quarter, making this their 5th consecutive quarter with at least 1 million or more net adds. In the past 15 months, T-Mobile has brought in a total of 7.6 million new customers, which is well, a lot. In fact, according to T-Mo’s numbers, they topped all of the other three major carriers combined in terms of postpaid phone adds. Not bad, right?

In other news announced today, Legere noted that T-Mobile has launched VoLTE nationwide. Just two months ago, they launched their first VoLTE market, which was Seattle, and were hoping to complete the full rollout by the end of the year. Clearly, they topped that prediction or expectation or timeline, whatever you want to call it. To date, T-Mobile customers have made more than 52 million “crystal-clear” calls over VoLTE, thanks to devices like the LG G Flex, Galaxy S5, and Galaxy Note 3.

Finally, T-Mobile has been “aggressively” rolling out their Wideband LTE, upgrading their 2G network to LTE, and getting their new low-band 700MHz A-Block spectrum ready. Legere points out in his post that they have only held this spectrum for three months yet are already equipping sites to handle it and testing devices. This low spectrum should greatly improve in-building LTE connections and coverage outside of metro areas, two things we all constantly complain about when it comes to T-Mobile’s coverage.
